Crossrail C360 Shafts

Scope of works

The Mile End, Eleanor Street, Limmo, Fisher Street and Stepney Green shafts were part of the Crossrail scheme and entailed the construction of new access, egress and ventilation intervention shafts at each location with associated head house buildings and tunnel adits.

The Kilnbridge scope varied between the shafts but generally included structural steelwork design, reinforcement detailing, temporary works design and the construction of reinforced concrete cores within the shafts and above ground. Kilnbridge also delivered reinforced concrete and composite slabs and steel-framed infill structures and, in the case of Eleanor Street, a steel-framed head house building.

Also included in the works are adit collars, diaphragm wall cutting, shaft capping beams and associated civils works, drainage and waterproofing.
